4.1 material

Question 1

Use the rule a^n a^m= a^n+m
Solve 2^3 times 2^2

Answer 1

2^5

Question 2

Use a^m/a^n= a^m-n
Solve 5^4/ 5^1

Answer 2

=5^3

Question 3

(a^n)^m=a^nm
Solve (3^2)^3

Answer 3

= 3^6 multiply exponent 2 to 3

Question 4

(a^n)^m = a^nm
Solve ((x+2)4)^2

Answer 4

=(x+2)^8

Question 5

(ab)^n = a^n b^n
Solve (2x)^3

Answer 5

2^3 x^3

Question 6

(ab)^n= a^n b^n
(xy)^2

Answer 6

x^2 y^2

Question 7

(a/b)^n = a^n/ b^n
Solve (x/2)^3

Answer 7

x^3/ 2^3
How: x times x times x/ 2 times 2 times 2= x^3/ 2^3

Question 8

Exponent of zero a^0=1 a can never equal zero
3^5/ 3^5 explain how

Answer 8

because it will be three 5’s divide by three 5’s three goes into three once therefore proves 3^0=1
