What is the difference written in scientific notation? 0.00067 - 2.3 x 10^5

shepuryov [24]

0.00067=67X10^5 so

67X10^5-2.3X10^5

64.7X10^5 which can be expressed as:

6.47X10^6

(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)

Simplify the following expression 5-⁵/2 x 5⁹/2

yarga [219]

Given:

Consider the given expression is

$5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}$

To find:

The simplified form of the given expression.

Solution:

We have,

$5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}$

Using properties of exponents, we get

$=5^{-\frac{5}{2}+\frac{9}{2}}$ $[\because a^ma^n=a^{m+n}]$

$=5^{\frac{-5+9}{2}}$

$=5^{\frac{4}{2}}$

$=5^{2}$

$=25$

Therefore, the simplified form of given expression is 25.
