Answer:

2³ = 8

Step-by-step explanation:

According to the laws of exponents, when raising a power to another power, you need to multiply the exponents. After you multiply each set of exponents by the additional power, then it become a multiplication problem where the base is the same. When multiplying exponents with the same base, you keep the base and add the exponents:

$(2^{3})^{7}*(2^{-9})^{2}=2^{21}*2^{-18}=2^{21+-18}=2^{3}$

Find the area, please help me, having a hard time getting through tonight’s homework. Complex/Compound area. Thanks!

Digiron [165]

Since the bottom shape is a semi-circle, the 3yd is the radius making the triangle's area 7 x 3 / 2 = 10.5

The semi-circle's area is $\pi$ $3^{2}$ /2 = 14.14

Combined, you get an area of 10.5 + 14.14 = 24.64 $yd^{2}$
