Question

evaluate the following for a=5,b=-4,c=10 b^3+2c^2 b tell​

Answer 1

Given,

a = 5; b = (-4); c = 10

To find :-

${b}^{3} + {2c}^{2b}$

$= {( - 4)}^{3 } + {(2 \times 10)}^{(2 \times - 4)}$

$= ( - 64) + {20}^{ - 8}$

$= ( - 64) + \frac{1}{ {20}^{8} }$

From here you can find the exact value if you want
