(7.8*10 to the 12th power)*800=(7.8*10 to the 10th power)*80,000
Directions:tell whether each equation is true or false. if false, write the inequality in like terms
I don't remember how to start multiplying.
Well you see Bob, first you would use the commutative property and change it to some thing like this: (7.8* 800) *10 to the 12th= (7.8*80,000) *10 to the 10th.
(7.8*10 to the 12th power)*800
= 7.8*800* 10^12
= 62400 * 10^12
= 6.24 * 10^15
(7.8*10 to the 10th power)*80,000
= 624000 * 10^10
= 6.24 * 10^14
so what do you think ?
To start multiplying, you will need to multiply the numbers before the multiplication sign (the asterisk "*") and then multiply the numbers after the multiplication sign separately.
Let's break down the first equation: (7.8 * 10^12) * 800.
1. Multiply the numbers before the multiplication sign:
7.8 * 800 = 6,240
2. Multiply the numbers after the multiplication sign:
10^12 remains the same.
So, the first equation simplifies to: 6,240 * 10^12.
Now, let's break down the second equation: (7.8 * 10^10) * 80,000.
1. Multiply the numbers before the multiplication sign:
7.8 * 80,000 = 624,000
2. Multiply the numbers after the multiplication sign:
10^10 remains the same.
So, the second equation simplifies to: 624,000 * 10^10.
To determine if these equations are true or false, we need to compare the values of both equations.
If (6,240 * 10^12) is equal to (624,000 * 10^10), then the equations are true. Otherwise, the equations are false.
Let's evaluate the two expressions:
6,240 * 10^12 = 6,240,000,000,000 (since 10^12 means multiplying by 10 twelve times or adding twelve zeros)
624,000 * 10^10 = 6,240,000,000,000 (since 10^10 means multiplying by 10 ten times or adding ten zeros)
Since the values of both expressions are the same, we can conclude that the equations are true.
