Possible my last brainliest if its right question idk may be more but this one is harsh for me

Correct Solution: He read 1.5 pages per minute.


Error Analysis: You should’ve divided 3 by 2 not 300. There are 300 pages in the book total. This information is irrelevant to the question. Cole reads 3 pages in two minutes. So you divide 3 by to to find out how many pages he reads per minute. 3/2=1.5

Write x4 * x2 without exponents.
AveGali [126]

Hey there!

It’s very much impossible to make this equation without it being an exponent because the result has an exponent in it itself

x⁴ × x²

= (x × x × x × x) + (x × x)

≈ x⁴ ⁺ ²

≈ x⁶

Therefore, the answer should be: x⁶


Good luck on your assignment & enjoy your day!
