The answer is 2 x 10^4 or 2 to the power of 4 (4th power) where;
2 x 10 x 10 x 10 x 10
2 x 10 =20
20 x 10= 200
200 x 10 = 2000
2000 x 10 = 20 000
Expressing a number to a single digit integer times a power of 10 is also writing a number in scientific form,where the number is multiplied by 10 to nth "power". Scientific notation is also called standard index form whereby, too large or too big numbers.
In writing the scientific notation of a number it follows this form: m x 10^n ( m is multiplied to 10 to the power of n) where, m, the coefficient, is the real number and n is the exponent integer.<span><span /></span>

answer:
x = 4
or 5.6568
step-by-step explanation:
- know the formula and plug in
formula: a^2 + b^2 = c^2
- now plug in what we have
- whatever the RIGHT ANGLE points to is the HYPOTENUSE or c
- the other two sides are the "legs" or a and b
a^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4
- in this case, b would be used as x
x = 4 or 5.6568 (exact value)
