10^4=10000 10000*5.2= 52,000
0.000391 is the decimal equivalent.
which expression is equivalent to (3 x 10^3) (5 x 10 ^5) sorry that is what i ment
The number 15,000,000,000,000,000,000,000,000, written in scientific notation, is equivalent to 1.5 x 10^25. This means that you move the decimal point 25 places to the right to get the original number. In terms of powers of ten, this number can also be expressed as 15 x 10^24.
If zero is permitted as the first digit then the number of combinations is 10 x 10 x 10 x 10 x 10 = 100000 If zero is not permitted then the number of combination is :- 9 x 10 x 10 x 10 x 10 = 90000
The word "X" does not have a specific meaning in number form. However, in Roman numerals, "X" represents the number 10.
121,010 :)
It is 320000000 or 3.2*10^8.
The number equivalent of 5 moles of potassium ions (K+) is 5 x Avogadro's number, which is approximately 3.01 x 10^24 potassium ions.
Per cent or percentage of a number is equivalent to the same number of hundredths of that number. 10% of 1380 = 1380 x 10/100 = 138.
x (x - 8) = 2xx2 - 8x = 2xx2 - 8x - 2x = 0x2 - 10x = 0x (x - 10) = 0The equation is a true statement if either factor = 0.x = 0(x - 10) = 0 ==> x = 10========================> Does [ x = 10 ] work ?x (x - 8) = 2x ?10 (10 - 8) = 2 (10)10 (2) = 2020 = 20 Yes.
10^4=10000 10000*5.2= 52,000
It is already a fraction: 1/5 (= 2/10)The decimal equivalent is 0.2To create an equivalent fraction to 1/5 multiply the numerator (top number) and denominator (bottom number) by the same number, examples:By 2:1/5 = (1 x 2)/(5 x 2) = 2/10 By 3:1/5 = (1 x 3)/(5 x 3) = 3/15 By 5:1/5 = (1 x 5)/(5 x 5) = 5/25 By 10:1/5 = (1 x 10)/(5 x 10) = 10/50 So 2/10, 3/15, 5/25 & 10/50 are all equivalent to 1/5
There are an infinite number of them. 2/10 4/20 10/50 20/100 Take 1/5 and multiply by x/x and get 1x/5x and put anything in for x and you get an equivalent fraction. ■
Multiply the numerator and denominator (top and bottom numbers) by the same number creates equivalent fractions: 2 ⇒ (1 x 2)/(10 x 2) = 2/20 5 ⇒ (1 x 5)/(10 x 5) = 5/50 123 ⇒ (1 x 123)/(10 x 123) = 123/1230 575 ⇒ (1 x 575)/(10 x 575) = 575/5750 etc are all equivalent to 1/10
0.000391 is the decimal equivalent.
0.15 x 10 = 1.5 0.15 x 100 = 15 0.15 x 1,000 = 150
