Answer:
−
5.23
×
10
7
Step-by-step explanation:
In scientific notation, numbers are written in the form
a
×
10
b
, where
a
is the "pre-exponential" part and
10
b
is the "exponential part".
Your number in decimal form is
-52,300,000
.
The negative sign remains unchanged.
To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point.
So,
-52,300,000
becomes
-5.230,0000
.
The trailing zeroes are not significant, so
-5.230,0000
becomes
−
5.23
.
We moved the decimal point seven places, so the exponent is
7
.
We moved the decimal point to the left, so the exponent is positive.
The exponential part is therefore
10
7
.
-52,300,000
=
−
5.23
×
