Question

Evaluate when a=2, b=-3, c=1/2, and d=10

Answer 1

whats the expression ?

Answer 2

\[\left( a ^{b}b \right)^{3}\div a ^{2}bc ^{4}\]

Answer 3

sorry for not writing the expression faster

Answer 4

ok, lets take one by one
a^b = 2^(-3) = ?

Answer 5

.125

Answer 6

\[(a ^{b}b)^{3}=(2^{-3}(-3))^{3}=(\frac{ 1 }{ 2^{3} }(-3))^{3}=(\frac{ -3 }{ 8 })^{3}\]

Answer 7

\[a ^{2}bc ^{4}=2^{2}(-3)(\frac{ 1 }{ 2 }^{4})=\frac{ 2^{2}(-3)1^{4} }{ 2 }\]

Answer 8

but in decimal form that = -.052734375

Answer 9

I got .0197753906

Answer 10

so, \[(\frac{ -3 }{ 8 })^{3}:\frac{ 2^{2}(-3)1^{4} }{ 2 }=\frac{ (-3)^{3} }{ 8^{3} }\times \frac{ 2 }{ 2^{2(-3)1^{4}} }\]

Answer 11

\[\frac{ (-3)^{3} }{ 8^{3} }\times \frac{ 2 }{ 2^{2}(-3)1^{4} }\]

Answer 12

no need to change it into decimal

Answer 13

let it in fraction

Answer 14

thx ☺

Answer 15

but i got 81/2048?? is that even correct

Answer 16

\[\frac{ -27 }{ 512 }\times \frac{ 2 }{-12 }\]

Answer 17
