simplify 200pi(r)^24r

Solution

simplify

200 \cdot π (r)^{2} \cdot 4 r

Solution

800 π r^{3}

Solution steps

200 π (r)^{2} \cdot 4 r

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

r^{2} r = r^{2 + 1}

= 200 π 4 r^{2 + 1}

Add the numbers:

2 + 1 = 3

= 200 π 4 r^{3}

Multiply the numbers:

200 \cdot 4 = 800

= 800 π r^{3}
