Question

Find the value of m so that (-5)m + 1 × (-5)4 = (-5)7

Answer 1

By doing in bodmas rule the value of m is done by rule
The value here the m is 3

Answer 2

Given equation is

$(-5)m + 1 \times (-5)4 = (-5)7$

From the above equation we have to find the value of $m$

For this we have to solve the equation.

$-5m+1(-20)=-35$

$-5m-20=-35$

Taking negative sign common from all the values.

We get,

$5m+20=35$

Taking $20$ from LHS to RHS we get,

$5m=35-20$

$5m=15$

$m=3$

Therefore, the value of $m$ is $3$
