Answer:

We just have to solve each power.

8^{2} = 8 \times 8 = 64\\10^{-2} =\frac{1}{10^{2} } =\frac{1}{100}=0.01 \\(-4)^{4}=(-4) \times (-4) \times (-4) \times (-4)=256 \\(-6)^{4}=(-6) \times (-6) \times (-6) \times (-6)=1,296

Remember, to solve a power, we just need to multiply its base as many times indicates its exponent.

It's important to know that the negative exponent indicates a position, that's why in the second exercise we needed to change the position of the power to continue.

A rectangle has an area of 216.24 cm2 and a height of 15.9 cm. How long is the base of the rectangle ?
Helga [31]
The formula for the area of a rectangle is A = bh.
Substitute 216.24 for A (area) and 15.9 for h (height).

A = bh
216.24 = b(15.9)
÷ 15.9      ÷ 15.9            Divide 15.9 on both sides.
13.6 = b

So, the base of the rectangle is 13.6 cm.
