Multiply and simplify if possible.<br> sqrt 5x(sqrt x-5 sqrt 5)
RSB [31]
Making the assumption that your problem looks like this,
\sqrt{5x}(\sqrt{x}-5\sqrt{5})

we use the distributive property to multiply:
\sqrt{5x}\times \sqrt{x}-\sqrt{5x}\times5\sqrt{5}&#10;\\&#10;\\ \sqrt{5x^2} - 5\sqrt{25x}&#10;\\&#10;\\ x\sqrt{5}-25\sqrt{x}

Express this is scientific notation
Vitek1552 [10]
Place the decimal point right after the first nonzero digit, which is 3. 

So you'll go from this 0.003045 to this 3.045 after this move.
 
Now ask yourself: "how many spots must I move the decimal point to get back to 0.003045?"

The answer is "3 spots to the left"

The exponent of the final answer is -3
The negative indicates "move left" and the 3 tells us how many places to move the decimal

Therefore, 0.003045 = 3.045 \times 10^{-3}

Answer: Choice C)
This is assuming you meant to write the -3 as an exponent
