Question

If m=2 and n=3 then 10m2 -9n3=77. justify your answer

Answer 1

Answer:

this cannot be true

step-by-step-explanation:

Given m=2 and n=3

we have to proved that

$10 {m}^{2} - 9 {n}^{3} = 77$

firstly putting the value of m and n in the given equation

$10 {m}^{2} - 9 {n}^{3}$

we get

$10 \times {(2)}^{2} - 9 \times ( {3)}^{3} \\ = 10 \times 4 - 9 \times 27 \\ = 40 - 243 \\ = - 203$

the answer is -203 which is not equal to 77 which is a contradiction so the above equation is wrong
