To write ( 7.7 \times 10^{-10} ) in standard form, you express it as a decimal number. This means moving the decimal point 10 places to the left, resulting in ( 0.00000000077 ). Therefore, in standard form, ( 7.7 \times 10^{-10} ) is ( 0.00000000077 ).
-2.56 times 10 cubed in standard form is -2.56 x 103
To write (1.02 \times 10^1) in standard form, you simply multiply (1.02) by (10). This results in (10.2). Therefore, the standard form of (1.02 \times 10^1) is (10.2).
5.23 times 10 to the 6 in standard form is written as: 5.23 x 106
To write the numbers 50,000,000,000, 200,000, and 30,000 in standard form, you express each number as a coefficient multiplied by a power of ten. The standard form of 50,000,000,000 is (5.0 \times 10^{10}), for 200,000 it is (2.0 \times 10^{5}), and for 30,000 it is (3.0 \times 10^{4}).
To write 10 to the seventh power in standard form, you need to multiply 10 by itself 7 times. This results in 10,000,000. Therefore, 10 to the seventh power in standard form is 10,000,000.
3.0 × 105 written in standard form is 300,000
32,400
324,000
To write 0.489 in standard form, you express it in the form of ( a \times 10^n ), where ( 1 \leq a < 10 ) and ( n ) is an integer. For 0.489, you can rewrite it as ( 4.89 \times 10^{-1} ) since moving the decimal point one place to the right increases the exponent by -1. Thus, the standard form of 0.489 is ( 4.89 \times 10^{-1} ).
1.86 times 10 to the 5th power = 186,000
