Question

(2x10^4) X (2x10^5) multiply without using exponents. would the answer not be (4x100)^9

Answer 1

u r almost

Answer 2

4*10^9

Answer 3

why would you leave the 10 and not multipy it?

Answer 4

2x10^4 means
2*10*10*10*10 (* means multiply, 2 times 10 times itself 4 times)
2*10^5 is 2*10*10*10*10*10
multiply it all togethter
2*10*10*10*10 * 2*10*10*10*10*10
we can change the order of multiplication 2*3 = 3*2 for example
2*2*10*10*10*10*10*10*10*10*10
2*2 is 4, so we can say
4*10*10*10*10*10*10*10*10*10
can you re-write using exponents?

Answer 5

u need to multiply only the first number in this case ok if there is any power function then u nedd to add 4+5 and the exponent should be constant

Answer 6
