27543000
question 4
convert 5.78 x 10⁻⁵ to standard notation.
0.00000578
question 5
multiply (6.8×10⁷)×(2.8×10⁶)
to type an exponent use the caret (^) for example:

Explanation:

Step1: Handle positive exponent conversion

$2.7543 \times 10^7$ means moving the decimal 7 places right:
$2.7543
ightarrow 27543000$

Step2: Handle negative exponent conversion

$5.78 \times 10^{-5}$ means moving the decimal 5 places left:
$5.78
ightarrow 0.0000578$

Step3: Multiply the scientific notations

First multiply coefficients, add exponents:
$(6.8 \times 2.8) \times 10^{7+5}$
$19.04 \times 10^{12}$

Step4: Adjust to proper scientific notation

Rewrite coefficient to be between 1-10:
$1.904 \times 10^{13}$

Answer:

1. $27543000$
2. $0.0000578$
3. $1.904 \times 10^{13}$
