Answer:
Below in bold.
Step-by-step explanation:
Use order of operations: the exponents are calculated first, then multiplication, then addition.
a. 1^2+2^3+3^4
= 1 + 8 + 81
= 90.
b. 4^2 * 2^4
= 16 * 16
= 256.
Answer:
90 and 256.
Step-by-step explanation:
1^2 + 2^3 + 3^4
Solve for the powers or exponents first.
1 + 8 + 81
Add the numbers.
= 90
4^2 × 2^4
Solve for the powers or exponents first.
16 × 16

6 * 0.7 = 4.2
4.2 * 0.7 = 2.94
2.94 * 0.7 = 2.058
2.058 * 0.7 = 1.4406
1.4406 * 0.7 = 1.00842
4.2 + 4.2 + 2.94 + 2.94 + 2.058 + 2.058 + 1.4406 + 1.4406 =
