I need to know the step by step and answer pls and thanks

(a)

In this question, you can simply just multiply the exponent of 2 and the exponent of 5, in order to get a power of 10.

(b) For this question, we need to organize the numbers as a fraction

We need to subtract the exponents from each variable. In and y, we need to subtract 3-1 to get . In and , we need to subtract 7-3 to get . Now, we can divide 12 and 6 normally to get 2. So, the answer would be .

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
