Step-by-step explanation:

There are two ways you can do this.

The first way, which is a little longer, is simply multiplying then reducing.

10=10/1, so the equation is 10/1*4/35

We then multiply 10*4 to get 40/35. then, 35 goes into 40 once and leaves 5/35, so we get 1. we can reduce this to 1

The second way is faster, where we find a common number in 10 and 35. We can see that both 10 and 35 are multiples of 5, so divide both by 5.

now, we get ×. now, we get 2(4)/7, to get . 7 goes into that once, so we have 1

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
