The sum of 3 and 4 is 7. The square of 7 is 7^2 = 49.

The square root of 144 is 12.

The square root of 169 is 13, since 13 * 13 = 169.

The square root of 256 is 16, since 16 * 16 = 256.

The square root of 625 is 25, since 25 * 25 = 625.

To add 3/4 and 2/5, find a common denominator, which is 20. Convert: 3/4 = 15/20 and 2/5 = 8/20. So, 15/20 + 8/20 = 23/20.

The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Their sum is 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 = 129.

The sum of the interior angles of a quadrilateral is always 360 degrees.

Surface area = 6 × side² = 6 × (3)² = 54 cm².

Surface Area = 6 * side² = 6 * 4² = 96 cm².

The total number of edges is half the sum of the degrees. Here, (3+3+2+2+2)/2 = 6.

Products A and B combined represent 60% of the total sales in the pie chart.

The total sales for Product A in Q1 is $1000 and in Q2 is $2000. Combined, they total $3000.

Surface area of a sphere = 4πr² = 4π(7)² = 196 cm².

Using the property (a^m)^n = a^(m*n), we get 2^(3*2) = 2^6.

Using the property a^m * a^n = a^(m+n), we get 5^(2+3) = 5^5.

Substituting x = 4 gives (4 + 3)(4 - 2) = 7 * 2 = 14.

2^3 = 8 and 3^2 = 9. Therefore, 2^3 + 3^2 = 8 + 9 = 17.

2^5 = 2 * 2 * 2 * 2 * 2 = 32.

3 cubed is 27 and 2 cubed is 8. So, 27 + 8 = 35.

Substituting x = 3 gives 4(3^2) - 16 = 4(9) - 16 = 36 - 16 = 20.

Calculating gives 5(2) - 3(1) = 10 - 3 = 7.

5^0 = 1, 5^1 = 5, 5^2 = 25. So, 1 + 5 + 25 = 31.

According to the order of operations, we first multiply 5 by 2 to get 10, then add 7 to get 17.

Using the property a^m * a^n = a^(m+n), we get 7^(2+3) = 7^5.

9^(1/2) is the square root of 9, which is 3.

Using the difference of squares: 9² - 5² = (9 - 5)(9 + 5) = 4 × 14 = 56.

Subtract 8 from both sides: -2x = -4. Divide by -2: x = 2.

Volume = π * radius² * height = π * 3² * 5 = 45π cm³.

Volume = π * r² * h = π * 3² * 7 = 63π ≈ 197.82 cm³.
