Question

if 52/160=13/(2^n×5^m)​

Answer 1

Answer:

n=3 m=1

Step-by-step explanation:

• 52/160=13/(2^n×5^m)
• 13/40=13/(2^n×5^m)
• (2^n×5^m)=40
• (2^n×5^m)=2^3×5
• so,
• on comparing
• n=3 and m=1

Answer 2

Answer:

4

Step-by-step explanation:

52/160=13/2^n5^m

52(2^n5^m)=160×13/52

2^n5^m=40

2^n×5^m=2^3×5^1

bases r equal then exponents must b equal

therefore n=3&m=1

n+m=3+1

n+m=4
