x = 7^2 = 49.

x = 7^3 = 343.

b^3 = 27, so b = 3.

64 = b^6, so b = 64^(1/6) = 2.

x^2 = 100, so x = 10.

x = 27^(1/3) = 3.

x^2 = 49, so x = 7.

x = 64^(1/6) = 2.

x = 81^(1/4) = 3.

log10(0.01) = -2, since 10^-2 = 0.01.

log4(16) = 2, since 4^2 = 16.

log10(0.01) = log10(10^-2) = -2.

log10(0.1) = -1 because 10^-1 = 0.1.

log10(1) = 0 because 10^0 = 1.

log10(100) = 2 because 10^2 = 100.

log10(1000) = log10(10^3) = 3.

log10(50) is approximately 1.7.

log2(1) = 0, since any number to the power of 0 is 1.

1/8 = 2^-3, so log2(1/8) = -3.

log2(16) = 4, since 2^4 = 16.

log2(32) = log2(2^5) = 5.

log2(8) = 3 and log2(4) = 2, so 3 + 2 = 5.

log3(81) = log3(3^4) = 4.

log4(16) = log4(4^2) = 2.

log5(25) = log5(5^2) = 2.

log7(49) = log7(7^2) = 2.
