Question

Using laws of exponents, simplify and write the answer in exponential form:

( 2power20÷ 2power15 ) × 2power3
(please explain too)

Answer 1

Answer:

2⁸

Step-by-step explanation:

(2²⁰ ÷ 2¹⁵) × 2³

First, we can use this law of exponent- (a^m ÷ a^n= a^m-n),

(2²⁰-¹⁵) × 2³

2⁵ × 2³

Next, we use this law of exponent- (a^m × a^n= a^m+n),

2⁵+³= 2⁸

Hope this helps.

Answer 2

Answer:

2⁸

Step-by-step explanation:

2 power 20 = 2²⁰

2 power 15 = ¹⁵

2 power 3 = 2³

AS PER THE LAWS OF EXPONENTS AND ALSO THE DMAS RULE,DIVISION IS FIRST

SO..WHEN WE HAVE SAME BASE WE SHOUKD SUBTRACT THE POWER IN CASE OF DIVISION. HERE 2²⁰ ÷2¹⁵=2⁵

NEXT IN MULTIPLICATION ✖ 2⁵×2³=2⁸

WE NEED TO ADD THE POWERS IN MULTIPLICATION
