Answers

Answer:

Step-by-step explanation:

The given expression is as following:

$((-8) - ((-14)/(-7) )^3)*(-3)+(-3)-34$

According to PEMDAS

calculate the process at the Parentheses first then the exponent.

So,

= $((-8) - (2 )^3)*(-3)+(-3)-34\n= ((-8) - 8)*(-3)+(-3)-34\n=(-16)*(-3)+(-3)-34\n=48+(-3)-34\n=48-3-34\n=11$

400 hundreds is the same as 4000

Answers

There are 40 hundreds in 4,000

Final answer:

400 hundreds is equal to 40,000, not 4,000. In the decimal number system, 100 is a unit ten times larger than ten (10). Therefore, 400 multiplied by 100 equals 40,000.

Explanation:

The statement '400 hundreds is the same as 4000' is in fact, incorrect. In the decimal number system, one hundred (100) is a unit that is ten times larger than ten (10). So, 400 hundreds would be equivalent to 40,000, not 4,000.

Here's a step-by-step explanation:

Remember that 1 hundred equals 100.
To find the total, you must multiply the number of hundreds (400 in this case) by 100.
So, 400 * 100 = 40,000.

Therefore, 400 hundreds equal 40,000, not 4,000. The understanding of place value is very essential in mathematics.
