Question

simplify the following two expressions........​

Answer 1

Answer:

simple

Step-by-step explanation:

in first question ..simply put the values of a and b in the given equation and you will get the answer...

in second question,

make 10as 5*2 and it will become as 5⁵*2⁵ from question

make 25as 5²

as we know that powers are minused if bases are dividing

and powers are plused if powers are multiplying

so,

also make 6⁵ as 2⁵*3⁵

now 3⁵-⁵ * 5⁵+²-⁷ * 2⁵-⁵

every base has power zero after solving

and

a⁰=1

then after multiplying 1*1*1

answer=1
