Question

Simplify and express the result as a power
of 5.
​

Answer 1

Answer:

1

Step-by-step explanation:

(2/5)10÷(2/5)7+3

(2/5)10-(7+3)

(2/5)10-10

(2/5)0

when power becomes 0 the answer becomes one .

thus,(2/5)0 = 1

and (1)5 = 1

so the answer is one

Answer 2

Answer:

1

Step-by-step explanation:

(2÷5)^10 ÷ (2÷5)^7+3

(2÷5)^10 ÷(2÷5)^10

when value is same then

(if multiply there power adds)

(if divide there power subtracts)

there is a divide

(2÷5)^10-10

(2÷5)^0

we know that any no have power 0

the answer will be 1
