Apply exponent properties involving products worksheets - Solution

Question 1 :

Simplify (5x²)⁴ x (2x)³

Solution :

  =  (5x²)⁴ x (2x)³

5⁴ = 5 x 5 x 5 x 5

2³ = 2 x 2 x 2

Since x⁸ and x³ are having same base, we can combine these terms.

Question 2 :

If 5 √5 x 5³= 5 ⁽ⁿ⁺²⁾ then find the value of n.

Solution :

Question 3 :

Simplify  (52 x⁶/13x⁻⁷)

Solution :

          =  (52 x⁶/13x⁻⁷)

We have negative power for the x term which is in the denominator.To make it as positive we are going to write it in numerator.

=  (52 x⁶x⁷/13)

=  4 x⁽⁶⁺⁷⁾

=  4 x¹³

Question 4 :

Simplify  (-7x²) (x⁴)

Solution :

 =  (-7x²) (x⁴)

=  -7 x⁽²⁺⁴⁾

=  -7 x⁶

Question 5 :

Simplify  (10 x y³ z²) (-2 x y⁵z)

Solution :

 =  (10 x y³ z²) (-2 x y⁵z)

=  -20 x^(1+1) y^(3+5) z^(2+1)

= -20 x²y⁸z³

Question 6 :

Simplify  (-5 xyz) (4 y⁵z) y³

Solution :

 =   (-5 xyz) (4 y⁵z) y³

=  -20 x y⁵y³z z

= -20 x y^(5+3) z^(1+1)

= - 20 x y⁸z²

Question 7 :

Simplify  (7 a b² c³) (¾ a b c⁴)

Solution :

 =   (7 a b² c³) (¾ a b c⁴)

=  (21/4) a^(1+1)b^(2+1)c^(3+4)

= (21/4) a²b³c⁷

Question 8 :

Simplify  (-4 a³) (-5 a⁴)

Solution :

 =    (-4 a³) (-5 a⁴)

=  20 a^(3+4)

= 20 a⁷

Question 9 :

Simplify  (2 a³) (¼) a⁴

Solution :

 =    (2 a³) (¼) a⁴

=  (2/4)a^(3+4)

= (1/2) a⁷

Question 10 :

Simplify  (10 p³) (7/25) p⁷

Solution :

 =   (10 p³) (7/25) p⁷

=  10(7/25)p^(3+7)

= (1/2) a¹⁰
