Question

1. Find the product:
9x³x 2x⁴​

Answer 1

Answer:

18x^7

Step-by-step explanation:

Using the laws of indices, we know that x^a x x^b= x^a+b

so 9x³×2x^4= 18x^7

Answer 2

Answer:

364.5

Step-by-step explanation:

x^3(9*2x)=0

9*2x=0

2x=9

x=9/2

putting x=9/2

9(9/2)*2(9/2)

81/2*18/2

=364.5
