Mauricio uses 2/5 cup of sugar to make one batch of chocolate chip cookies and 1/8 cup of sugar to make one batch of sugar cookies.

a. How much sugar does Mauricio need to bake both batches of cookies?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The answer is the first one

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
