Answer:
Rewriting
without an exponent we get 
Step-by-step explanation:
We need to rewrite the following without an exponent. 
We need to solve the exponent to find the result.
We know the exponent rule: 
Now using this rule to solve the equation:

So, Rewriting
without an exponent we get 
Answer:2
Step-by-step explanation:
Given
Physics problem requires 20 min
Math problem require 10 min
suppose x question of Physics and y questions of Math are done
so according to the question

Time require for x Physics problem 
Time require for y Math problem 
so,

On solving (1) and (2)
we get
and 
Maximum no of Physics question which can be solved is 2
A rhombus has two equal sides
