Final answer:
The expressions 7+3²-2•5 and (3/4+1/8) divided by 1/8 both simplify to the value of 6.
Step-by-step explanation:
To compare the expressions 7+3²- 2•5 and (3/4+1/8) divided by 1/8, we can simplify each expression separately.
For the first expression, 7+3²-2•5, we start by evaluating the exponent: 3² = 3x3 = 9. Then, we perform the multiplication: 2•5 = 10. Finally, we add the results: 7+9-10 = 6.
For the second expression, (3/4+1/8) divided by 1/8, we begin by finding the sum of the fractions: 3/4+1/8 = 6/8 + 1/8 = 7/8. Then, we divide this result by 1/8 by multiplying by its reciprocal: 7/8 * 8/1 = 7/1 = 7.
Therefore, the two expressions are equal and both simplify to the value of 6.
