Find the value of 333^{-3}.

What is the value of (4)2 (-4)^{-2} ?

What is the value of the following expression:

51×23×32? 5^{-1} \times 2^3 \times 3^{-2} ?

Scientific notation has two parts: a number (say aa) between one and ten, and that number multiplied by ten raised to the power b,b, where bb is a non-zero integer: e.g. a×10b, a \times 10^{b}, where 1a<101 \le a<10 .

Find the value of aa when you simplify the following expression in scientific notation to two decimal points:

(4.7×103)×(6.1×109).(4.7 \times 10^{-3}) \times (6.1 \times 10^{9}).

Find the value of (14)2 \left( \frac{1}{4} \right)^{-2} .
