How to write 778,000,000 in scientific notation
Anestetic [448]

To answer the question what is 77800000 in scientific notation let’s recall how to convert 77800000 to scientific notation as detailed on our home page.

When you split the number 77800000 into a coefficient and a power of 10 you do get 77800000 in exponential form, but there is an indefinite number of possibilities.

As you probably want 77800000 in normalized scientific notation, the coefficient or significand of 77800000 in scientific notation must be in the interval [1,10[.

As there are many ways to express 77800000 in scientific notation, in this post we mean 77800000 in normalized scientific notation, unless stated otherwise. Therefore:

77800000 in scientific notation = 7.78 × 107.

Ipatiy [6.2K]

Answer: 1, 3, 5, 2, 6, 4

Explanation:

The sympathetic nervous system stimulates many parts of the body for action during times of danger.

This signalling starts when the postganglionic neuron depolarizes, and postganglionic neuron releases acetylcholine, then the acetylcholine binds to nicotinic receptor in order to transmit impulse, and further the acetylcholine binds to sweat gland’s muscarinic receptor to disrupt or inactivate the action of acetylcholine. Finally, the neuron releases acetylcholine, and the neuron exits lumbar segment of spinal cord.

The danger has now been fully interpreted.
